New tool bar with nice order, ability to fold/unfold and what I like even more : possibility to search a tool by name. Nice update on Amphi last release. Good job Thibaut Gourdel and thanks for listening to users (especially when the user is myself). For everyone, if you don't know Amphi : it's a (young and WIP) visual python-based ETL. https://amphi.ai/

☀ Blog1 : Embarking on My PySpark Journey as a Data Engineer 🔥 Hi everyone, I am excited to embark on this journey of learning and exploring PySpark with all of you, starting with a deep dive into the fundamentals of PySpark and will be covering everything from initial setup to advanced level and I'm happy to hear any ideas, help, or fixes you have along with this journey. ✨ First Blog Topic: Before we dive into the world of PySpark, lets explore the basic introduction of Apache Spark.     1. What is Spark? 👉 Spark is designed to support wide range of task over the same computing engine. It is a unified analytics engine for large-scale distributed data processing. 👉 It is an open-source cluster computing framework, which handles both batch data and streaming data  👉 It does not have any separate storage or file system, it is limited to a computing engine       👉 Spark is much faster than Hadoop, because it does in-memory processing (spark hold the data in memory for processing while the Hadoop writes the data back to disk and read it again from disk to in-memory) 👉 Spark can work with different resource manager/Cluster manager. For eg. 🔥 Yarn 🔥 Mesos 🔥 Kubernetes 🔥 Standalone (Spark own cluster) 👉 Spark provides high level API or libraries for different languages like Python, Java, Scala and R    2. Why Spark?         👉 Speed: Spark can process large volumes of data at fast speed.        👉 Easy to use: Spark offers different languages and libraries as per the need of user.        👉 Versatility: It is not limited to one specific task, it can handle all sorts of tasks like analyzing data, running machine learning algorithms and processing streaming data in real-time.         👉 Reliability and scalability: Spark is highly reliable with built in fault tolerance mechanisms and scales seamlessly to handle increasing computational demands. In this blog post, I have covered the basic intro of Apache Spark. In the next blog I will be delve deeper into the Eco-system of Spark and its components. Stay tuned! I would love your thoughts on it, check it out when you get a chance Sanjeeb Mohapatra Rajas Walavalkar #Spark #DataEngineering #Learning

Christophe Pettus: An Interlude: Why you do not want to use C/POSIX locale. 🚫 **Steer Clear of C/POSIX Locales in PostgreSQL** 🚫 Ah, locales and character encodings—the cerebral yet deceptively chaotic realm of PostgreSQL that gets your neurons firing! 😅 If you're looking to spice up your database with unpredictable zaniness, then, by all means, embrace the C/POSIX locale. Here's why it's a rollercoaster you probably want to skip. Christophe Pettus eloquently points out that C/POSIX locale is great—if you live in a world of ASCII purists. But let's face it: that's as rare as a unicorn, especially if you're juggling mixed client encodings. Go down this path, and prepare for your data to speak in cryptic tongues. 🌐 🤷‍♂️ In an enlightening interlude (check his blog!), Christophe demonstrates how you can slip down this rabbit hole: set your client encoding to UTF8 and LATIN1, and watch your beautifully inserted "Í" turn into "é" faster than you can say "collation." 😲 And lest we forget, SQL_ASCII locale—where data goes to lose its identity completely. Just... don’t. Why invite chaos when harmony is just a sensible locale setting away? 🎶 Credit to the maestro, Christophe Pettus, for saving us from self-inflicted database mayhem: [his enlightening post](https://lnkd.in/eHq5eY_c). #PostgreSQL #DatabaseManagement #EncodingMadness You can find the full article here: https://postgr.es/p/6FR

What is Apache Flink ? Let's demystify it ! This is from the Official documentation. Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale. What is bounded and unbounded data streams ? Bounded data streams: The data has a clear beginning and ending, i.e data has bounds of data. E.g. a movie, a song, a file Unbounded data streams: This type of data is more real-time and does not have fixed limit / ending. E.g.- data from social media posts, live sports scores, or weather reports. Consider a viral video from Taylor Swift / Katy Perry. There will be many comments, likes, these events have to be processed in Real-time. What does stateful computation mean ? Flink manages state (data context) across multiple events efficiently. This feature is essential for complex processing tasks that depend on previous data. For E.g. - Managing transactions. Every transaction changes account balance. Flink can handle the dynamic updates to persist and update balance for the transactions. Also, whenever you hear distributed it means the computation / processing is spread over multiple machines. Exploring Flink in AWS very straightforward - https://lnkd.in/gaj3jH4Z GCP does not offer a specific managed service like AWS. There are couple of ways though - 1. Deploy Apache Flink on Google Kubernetes Engine ( GKE ) 2. Manually set up Flink clusters on Compute Engine virtual machines. 3. Google Cloud Dataflow can be used to run Flink applications since Apache Beam has a runner that supports Flink. Similarly in Azure, you can explore using - 1. HDInsight: Azure HDInsight is a cloud service that simplifies, enhances, and manages Apache Hadoop-based projects, including Apache Flink. 2. Azure Kubernetes Service (AKS): Similar to GKE on Google Cloud, AKS allows you to deploy containerized Flink applications using Kubernetes. Official website - https://flink.apache.org/ Learn more on the key use cases of Flink here - https://lnkd.in/e5F_b-ii 1. Event Driven applications 2. Data Analytics applications 3. Data Pipeline applications Guess the best part of Apache Flink, it's a nice Squirrel logo. Do share your experience with Apache Flink if you have used it or explored it ! #Apache #Flink #Data #Cloud #AWS #GCP #Azure #Stream #Batch

Here's a secret Snowflake tip 🤫: with the ability to host Notebooks on the new container runtime, we can now install arbitrary packages using !pip. 🔥 Yes, we can also install packages not available on the Anaconda Snowflake repo (with all the risks that come with it 😅). For instance, now you can install the Cinemagoer package and search the IMDb for all the movies containing the word "matrix" in the title 👇

🔊 Understanding Apache Kafka: A High-Throughput Distributed Messaging System Apache Kafka is a powerful platform for building real-time data pipelines and applications. The diagram illustrates how Kafka works by leveraging producers, brokers, and consumers in a distributed architecture. 📚 Kafka Environment Components: 1. Producers : push messages to the Kafka cluster, sending data from sources like web apps or sensors. ⚙ Example: In e-commerce, producers push new orders or user activity to Kafka for further processing. 2. Kafka Brokers : store messages in topics and ensure fault tolerance across the cluster. ⚙ Example: Brokers store real-time stock prices until consumers pull the data. 3. Consumers : pull messages from brokers, processing the data asynchronously. ⚙ Example: A consumer updates dashboards or triggers emails after processing orders. 4. ZooKeeper : coordinates the Kafka brokers, maintaining cluster health and synchronization. 📚 Real-World Use Case: Imagine a ride-sharing app like Uber. As a producer, the app pushes data (such as ride requests, locations, and status updates) to Kafka. Kafka brokers then store this data until the appropriate consumers (like fare calculation services, driver location tracking systems, or notifications services) pull the messages to process them in real-time. This ensures the system can scale to handle thousands of rides happening simultaneously, all while ensuring fault tolerance. 📚 Key Benefits of Kafka: Scalability: Kafka can handle a high throughput of messages across distributed clusters. Loose Coupling: Producers and consumers are independent, allowing for flexibility and scalability. Fault Tolerance: With brokers and Zookeeper managing the environment, Kafka ensures high availability. By decoupling data producers from consumers and ensuring reliable message delivery, Apache Kafka is an ideal solution for building event-driven architectures and real-time data pipelines.

❄️ I just finished reading the Snowflake paper and I found these decisions of the authors very interesting and effective, explaining its wide adoption: • 𝐒𝐞𝐩𝐚𝐫𝐚𝐭𝐞 𝐬𝐭𝐨𝐫𝐚𝐠𝐞 𝐟𝐫𝐨𝐦 𝐜𝐨𝐦𝐩𝐮𝐭𝐞: Makes it possible to scale and optimize each service independently, but still be tightly coupled. • 𝐃𝐢𝐝𝐧'𝐭 𝐫𝐞-𝐢𝐧𝐯𝐞𝐧𝐭 𝐭𝐡𝐞 𝐰𝐡𝐞𝐞𝐥: Chose the already state of the art technologies S3, EC2 and CloudHSM from AWS and used the saved time to improve other features. • 𝐒𝐢𝐦𝐩𝐥𝐢𝐜𝐢𝐭𝐲: Use only T-shirt sizes (X-Small to XX-Large) for selecting computing power no complex configs. • 𝐀𝐧𝐭𝐢𝐜𝐢𝐩𝐚𝐭𝐞 𝐮𝐬𝐞𝐫 𝐦𝐢𝐬𝐭𝐚𝐤𝐞𝐬: They can be rolled back using "Time Travel" feature. I highly recommend checking it out!

Spotting Postgres performance issues with Coroot 💡 🔗 https://lnkd.in/eUEP-EXH 🧑‍💻 Nikolay Sivko : "We spot a spike in the catalog‘s latency. To determine whether this anomaly is caused by a Postgres performance issue, we need to somehow compare the app latency with the DB latency. If these metrics correlate we can go deeper to find the reason for the degraded database performance."
